In the present study grain yields and grain protein content of spring barley grown in continuous cropping were evaluated. The trial was carried out in the years 2001-2006 in a sugar beet growing region on a site at Ivanovice na Hané. The varieties Akcent and Forum were grown in the years 2001-2003; Jersey and Prestige were grown afterwards (2004-2006). The treatments were as follows: stubble breaking, stubble breaking with a catch crop, straw incorporation into the soil, a catch crop with straw incorporation, straw burning, and organic fertilizer application. A statistically significant effect of year, treatment and previous crop on grain yields and grain protein content has been found. Low yields and low protein content were in treatments with straw incorporated into the soil.In the present study grain yields and grain protein content of spring barley grown in continuous cropping were evaluated.
